Operation principle
Explain in detail the operation principle of the present invention below also referring to Fig. 4.
By according to the present invention, by special-shaped portion 40 produce rotational symmetric between roll neck bushing 20 and roll neck 10
Cavity 12, produces bigger free space between roll neck bushing 20 and roll neck, and roll neck bushing 20 can be on the position of power effect
It is extended in this free space.
Specifically, in the rolling work in rolling-mill housing, by roll-force f at least substantially vertically upwIt is applied to
On upper (support) roll, and simultaneously by least substantially roll-force f vertically downwardwIt is applied to down on (support) roll.
Each half of this roll-force is delivered on roll neck by the body of roll, and thus the roll neck in upper mounting blocks is pressed upward and in lower installation
Roll neck in block is pressed downward.
According to effect chain, roll-force continues through roll neck bushing, holding between roll neck bushing and bearing insert from roll neck
Carry oil film and bearing insert is passed on mounting blocks.By mounting blocks, roll-force is continued to be delivered to that mounting blocks are supported on rolls
In machine frame.
Mounting blocks and the bearing insert being bearing in mounting blocks ideally should be considered can not bend with respect to roll-force
Take and incompressible.That is, mounting blocks and bearing insert sustain the rolling being respectively half being applied to thereon completely
Power fw/ 2 (aktio), reversely keep bearing f numerically always identical but in opposite direction for this mounting blocks with bearing insertl
(reaktio).
With roll-force f of very little during rolling workwLoad roll neck to have caused, roll neck 10 is being rolled with roll neck bushing 20
Power f processedwSide press up to carry on oil film 30, and oil film 30 is pressed onto on bearing insert 51 and mounting blocks；See Fig. 2.But
Here, roll neck bushing 20 bumps against on incompressible carrying oil film 30, the bearing insert 51 that can not surrender and the peace that can not surrender
Dress block 50 hinders oil film, and this offsets up in the side of roll-force.As a result, reverse bearing flRoll neck bushing is therefore hindered to exist
The side of roll-force offsets up.
Combine towards the cavity 12 of roll neck 10 with according to the present invention, roll neck bushing 20 is illustrated above in itself
(rolling) power acts on the weakest link in chain.
Because roll neck bushing 20 can not avoid roll-force, in the case of bearing load during rolling work, may result in roller
The elastic deformation of neck bushing 20.Roll neck bushing 20 passes through roll-force fw/2Or rightabout bearing flIt is deformed to (original)
In cavity 12 and here flattens.Farthest flatten, until roll neck bushing 20 is pressed onto on roll neck 10 and is supported by roll neck.
Roll neck bushing 20 local elasticity ground matches and is again deformed back its initial condition after unloading with the special-shaped portion 40 of roll neck.Logical
Cross and flatten, increase the pressure application surface between roll neck bushing 20 and bearing insert 51.In roll neck bushing 20 and bearing insert
It is provided with carrying oil film 30, it forms so-called fluid power filmatic bearing between 51.Due to the increase of pressure application surface, according to this
Bright rolling device makes the bearing capacity of the fluid power filmatic bearing between roll neck bushing and bearing insert improve.
In practice, roll-force or bearing are not point-like ground or linearly act on, but are acted in the form of waveform power.
Waveform power has facial extension on circumferential and axial direction.By the gentle pressure effect related to this of the change of roll neck bushing
Face increases, and the waveform power for facial extension achieves the significant bearing capacity of rolling device and improves.
For example pass through hot charging with respect to roll neck bushing in the state of non-bearing load with pretightning force and roll neck power transmission
The rolling device connecting, the bearing capacity of the rolling device according to the present invention is clearly more powerful.Due to the cavity according to the present invention, it is
The roll neck bushing elasticity required power that flattens is made to load less than the structure between bearing insert and roll neck with pretension.In pretension
Structure in, in order to realize the identical deformation of roll neck bushing, need bigger power.
In other words:
Due to the wall thickness of the relative thin of roll neck bushing 20, the deformation under a load at the inner peripheral surface 21 of roll neck bushing 20
It is not changed in ground, similarly occurs at the outer peripheral face 22 of roll neck bushing 20, and thus make in roll neck bushing 20 and bearing
The pressure face contrary with power effect between bushing 51 increases/expands.This make again lubrication film pressure distribution more uniform, thus
Bigger power can be born and power can be made to be distributed wider, and the surge pressure in carrying oil film 30 is less than bearing insert
Material or the material of bearing metal lining on bearing insert ultimate value.Therefore, according to assembly of the invention so that
The bearing capacity of the hydrodynamiclubrication film between roll neck bushing 20 and bearing insert 51 or filmatic bearing improves.
